Well, make that twice I replied to Isaac instead of the list:

I recall an ingenious device from Sanderson, that anybody can make its own, 
these are 2 rules (of different height) made of strips of thick paper where the 
spacing at the end of the key is marked with the partial series enlighten. 
The 2 strips can be used one at the lower note of the interval to be tested and 
the other on the highest, and the scale show immediately where the partials 
are coincident. 
Just last week I made such a device (in minutes, out of poster board) for my 
PTG chapter tuning demonstration. I think everyone should have one until they 
are facile with the partial series and coincident partials. I gave credit to 
Jim Coleman, Sr., because that's who my fuzzy memory contained as the first 
person I saw use it. Was Al Sanderson actually the first? It's so clever I would 
like to credit the right person.
